Answer:
C
Step-by-step explanation:
Median of triangle: It is a line segment joining a vertex to the midpoint of the opposite side.
Consider ΔABC, point F id the midpoint of line segment AB and E is the midpoint of luine segment AC.
Draw line segments FC and BE(medians of triangle). G is the point where line segment FC and BE meet. Now, Join AG.
Let H be the point outside the ΔABC and AG passs through the point H such that AG intersects BC at D. BH and HC are dashed lines.
We need to show that D is the midpoint of BC. The correct logical order for proof will be:
III. GC is parallel to line segment BH and line segment BG is parallel to line segment HC.
IV. Line segment FG is parallel to line segment BH and line segment GE is parallel to line segment HC.
I. BGCH is a parallelogram as opposite sides are parallel (from III.)
II. Since, diagnols of a parallelogram bisect each other. Henc, we get BD=DC.
Therefore, D is mid pont of BC.
It implies that AD is also a median.
Hence, all the three medians that are: BE,FC and AD passes through a common vertex G.
Figure 1 is the original figure, while figure 2 is
modified, so that a triangle and a rectangle can be easily observed.
The area of triangle and rectangle represents the
total number of cubic feet of storage multiply by the number of days of storage
usage.
Hence
Total Area = Area of triangle + Area of rectangle
= 30 x 10,000 + ½ 30 x (30,000 – 10,000)
= 300,000 + 300,000
= 600,000
As 10 cubic feet of storage cost $5 for a day, so
total amount company have to pay
<span>= (5 x 600,000) / 10 = $300,000</span>
Answer:

Answer:
slope of 1/4, y = 1/4 * x
Step-by-step explanation:
Answer:
x=-4.5 or x=-2/9(fraction)
Step-by-step explanation:
3x^2-6x-2=0 simplify so add 3 minus 6 then do ^2
-9x-2=0 Add 2 on both sides
-9x=2 divide by -9 on both sides
x=-4.5 or x=-2/9
